In what Bloomberg News called a “wide-ranging interview” with EPA chief Scott Pruitt, he indicated the agency does not intend to let California set the agenda for national emission limits on vehicles.

Bringing California into line would require eliminating the state’s 50-year history of regulating vehicle emissions within its borders by revoking the current waiver to national rules, the latest in dozens of such waivers spanning decades.

The Trump Administration’s EPA head also said his agency is not “presently” looking at plans to extend emission regulations for motor vehicles beyond 2025.

In the Bloomberg report on Tuesday, Pruitt’s comments seem to indicate that the agency will respond aggressively to automakers’ pleas for reductions in the corporate average fuel economy rules for 2022 through 2025 that the makers agreed to in 2012.

Those rules were subject to a midterm review.

That review led to a Technical Assessment Report issued by the agency in July 2016, which concluded automakers had met the 2012 through 2017 standards more easily and at lower cost than projected, and would be able to do so through 2025.

Despite the fact that the CAFE rules are based on “footprint,” which larger vehicles subject to lower fuel-efficiency requirements, automakers claim the pronounced market shift from passenger cars to crossovers and light trucks makes the rules too challenging to meet.

The industry, through its lobbying arms, has also pleaded for a single national standard, rather than one set of limits for roughly two-thirds of U.S. buyers and a stiffer set for residents of the dozen or so states that have adopted California’s tougher emission rules.

Under the Obama Administration, that fate was avoided with minor concessions by the powerful California Air Resources Board and an agreement by the auto industry to meet those standards nationally.

Two of the Detroit Three were then freshly out of bankruptcy and government-backed restructuring costing billions of dollars. Now, the industry suggests the combination of more truck and SUV sales, low sales to date of electric vehicles, and California’s plan to stick with 50 years of emission reductions poses an impossible challenge—and the EPA head concurs.

“California is not the arbiter of these issues,” Pruitt told Bloomberg, and the state “shouldn’t and can’t dictate to the rest of the country what [vehicular carbon-dioxide emission] levels are going to be.”

Trump’s EPA administrator, meanwhile, is a climate-science denier who sued the agency he now runs more than a dozen times, while attorney general of Oklahoma, to prevent it from enforcing emission limits on that state’s powerful fossil-fuel industry.
